Value Collection ZMSCH70125 O-ring Dash 125 Nbr 70

Product Description

The VALUE COLLECTION ZMSCH70125 is a Dash 125 O-ring manufactured from Nitrile Butadiene Rubber (Buna-N) with a round cross section. It measures 1.313 inches inside diameter, 1.500 inches outside diameter, and 0.094 inches thick. The compound carries a Shore A hardness rating of 70, placing it in the hard range. Buna-N is the most widely used O-ring elastomer in trade applications. It delivers excellent resistance to petroleum-based fluids along with strong compression set performance and solid tear and abrasion resistance. Licensed plumbers, HVAC technicians, and hydraulic service technicians regularly use this O-ring in fluid-sealing applications across a broad range of systems.

This O-ring is suited for static and dynamic sealing applications involving petroleum products, hydraulic oils, fuels, and lubricants. It performs within a temperature range of -40 degrees F to 250 degrees F, making it appropriate for a wide variety of residential and light commercial plumbing, HVAC, and hydraulic equipment installations. It should not be stored in direct sunlight or near motors or electrical equipment that may generate ozone, as ozone exposure degrades Buna-N compounds over time. It is sold in a package quantity of 100 pieces.

Installation Notes

This O-ring is installed by licensed plumbers, HVAC technicians, or hydraulic service professionals following applicable codes such as the IPC and IFGC. Depressurize and isolate the system before removing any fitting or component that retains this seal. Inspect the mating groove for burrs or corrosion before installing the replacement ring. Do not expose the O-ring to ozone-generating equipment during storage or installation.
